It could be a big deal. When I was recovering from an Achilles injury, socks were created just enough extra pressure that it made things worse. When I didn't wear socks I was in a lot less pain.
To the OP, while you are building up your callouses try avoiding running through puddles. You'll get some blisters but not for very long. Feet callous quickly.
